I see that you've uploaded an image containing a set of mathematical problems. Let's break down the tasks to solve them step by step:

1. Tentukan titik-titik kritis dari fungsi dan interval berikut ini (Find the critical points for the given functions over specified intervals):

   • For each function $f(x)$, we need to find the derivative $f'(x)$, set it to zero, and solve for $x$. Critical points occur where $f'(x) = 0$ or where $f'(x)$ is undefined within the given interval.

2. Tentukan nilai maksimum dan minimum (Find maximum and minimum values):

   • Using the critical points found in part 1, along with the endpoints of the interval, we need to evaluate the function at these points to determine the maximum and minimum.

3. Tentukan dimana fungsi berikut monoton naik dan monoton turun (Determine where
